Experimental Facilities
FDTD software for simulations
We have the Three-dimensional Finite-Difference Time-Domain-FDTD (Ansys ) simulation facility in our lab. It is nothing but solving Maxwell's equations at nanoscales. It is a very powerful tool to design any complex geometry. First, we design the system and predict the expected results before proceeding into the realistic experiment. One can enhance the efficiency of the experiments based on this.
Class 100/1000 Local
Clean Booths
It is essential to avoid any unwanted dust contaminants that are sitting on the optical nanofibers/tips (ONF/ONFTs) as well as equipment since they degrade the quality of the surface and the transmission through the fiber. Under these clean room conditions, one can avoid all kinds of dust up to 99% throughout the experiments.
Tabletop Fumehood
This facility fabricates the ONFs/ONFTs using chemical etching techniques under the control of temperature and pressure for nanophotonic applications. In this method, we also fabricate high-quality micro/nanofibers
Customized Optical Nanofiber fabrication machine
We have an excellent facility of highly customized Heat and Pull machines for fabricating high-quality nanofibers (ONFs) by maintaining an adiabatic condition for quantum photonic applications. Using this, one can fabricate the ONFs of sub-wavelength diameters below 300 nm.

EMCCD based Spectrometer
We have a high resolution and completely computerized spectrometer of highly sensitive cooled EMCCD camera of high quantum efficiency of 95% for detecting fluorescence photons to confirm the single photon emission spectrum.
Time Correlated Single Photon Counting Module (TCSPC)
Since we are working on the manipulation of single photons emitted from the single quantum emitters (SQE), it is necessary to confirm the quantum nature of the photons by observing the anti-bunching nature as well as the single photon emission from the single quantum emitter by studying/observing the arrival times of the single photon via time correlation measurements.
Motorized translational
X,Y and Z-Stages
It requires high-precision displacement of nanostructures and deposition of a single quantum emitter on the surface of ONFs/ONFTs since the scales of this system are in nanoscales. These positioners can control the x, y and z-directions with a maximum travel range of 30 mm with resolution of 100 nm in each step.
Microfluidic Technology
This technology is for the precise positioning of the nanoscale particles such as single quantum dot, Au-nanoparticles or mixture of these on the desired position of such a low diameter ONFs and dipping of the ONFs into the solutions, injecting the a low viscous liquids into the hollow core region of thin nanocapillary fibers etc.

Inverted Microscope
The primary purpose of this one is to simultaneously view the contact between the two nanoscale components through a high numerical aperture lens of the microscope.
